EL3041 - Introduction
Analog Input Terminal; 1 channel, 12 bits, 0 ... 20 mA, single-ended input
The job of the EL3041 analog input terminal is to supply power to measuring transducers located in the field, and to transmit analog measuring signals, electrically isolated, to the automation device. The voltage for the sensors is supplied to the terminals via the power contacts. The EtherCAT Terminal indicates overload via error LEDs.
The power contacts can optionally be supplied with operating voltage in the standard way or via a power supply terminal (EL9xxx) with electrical isolation. The input electronics is independent of the supply voltage of the power contacts.
The 0 V power contact is the reference potential for the input.
